Four new well-defined CuI complexes bearing a C2F5 ligand have been prepared and fully characterized: [(Ph3P)2CuC2F5] (2), [(bpy)CuC2F5] (3), [(Ph3P)Cu(phen)C2F5] (4), and [(IPr)CuC2F5] (5). X-ray structures of all four have been determined, showing that the C2F5-ligated Cu atom can be di- (5), tri- (2 and 3), and tetracoordinate (4). The mixed phen-PPh3 complex 4 is a highly efficient fluoroalkylating agent for a broad variety of acid chlorides. This high-yielding transformation represents the first general method for the synthesis of RCOC2F5 from the corresponding RCOCl. Four well-defined CuC2F5 complexes have been prepared and fully characterized, with [(phen)Cu(PPh3)C2F5] (phen=1,10-phenanthroline) proving to be a remarkably efficient fluoroalkylating agent for a broad variety of acid chlorides (see scheme). The procedure represents the first general method for the one-step conversion of RCOCl into valuable pentafluoroethyl ketones.

We have reported a new type of axially dissymmetric ligand, (R)-bis{(R)-2,2,2-trifluorohydroxyethyl}biphenyl ((R)-(R)2-1), which showed an excellent asymmetric induction in the reaction of Et2Zn to benzaldehyde. Now, a pentafluoroeth
